While watching Emma's family group they suddenly came across a Blue Whale in their path! Although Humpbacks stand up to Killer Whales and trumpet blow at them, Blue Whales are easily startled by Killer Whales, and flee the scene! If you watch closely in the second clip you can see the adult Blue Whale porpoising away, swimming at full speed out of the water on the other side of our boat in the upper left hand corner.
